Calculate dilutions quickly and easily with this online dilution calculator. It supports both mass/volume and molarity calculations.
How to Use
- Mass/Volume or Molarity: Choose the appropriate section.
- Enter Values: Input known values. Leave one field blank — the calculator determines the missing value from C₁V₁ = C₂V₂.
- Calculate: Click the “Calculate” button.
- Copy Result: Click the “Copy Result” button to copy the result to your clipboard.
- Clear: Click “Clear All” to reset.
Serial Dilution
Expand the Serial Dilution section to generate a table of sequential dilutions.
- Stock Concentration — starting concentration
- Dilution Factor — fold dilution per step (e.g., 2 for 2-fold)
- Number of Steps — how many dilutions to generate
- Volume per Step — total volume of each dilution
The table shows each step’s concentration, volume to transfer from the previous step, and volume of diluent to add.
Mass/Volume Dilutions
Uses C₁V₁ = C₂V₂, where C₁ = stock concentration, V₁ = volume from stock, C₂ = final concentration, V₂ = final solution volume.
Molarity Dilutions
Same formula (M₁V₁ = M₂V₂) with molarity. Supports mole-based units (mol, mmol, µmol, nmol) — enter molar mass to convert between moles and molarity.
Important Notes
- Assumes ideal solutions.
- Always use appropriate laboratory safety practices.
